New versions of the 15in MacBook Pro and 27in iMac are expected as early as 20 May, suggests a new report.

French site MacG, quoting its unnamed reliable sources who in the past have provided accurate information, reports that the 15in MacBook Pro will pack a modified processor and Force Touch trackpad introduced in the 13in MacBook Pro (Retina display) and 12in MacBook (Retina display) launched earlier this year.

Since the 13in MacBook Pro was updated with the latest processor, powerful graphics, faster flash, longer battery life and the new Force Touch trackpad, the 15in model should also received the same upgrades.

The report further suggests that the shipping timing of the high-end 15in MacBook Pro increased by a further two to three weeks. The shortage in supply suggests that Apple could be cutting down the production of the existing models or, it could be for the imminent launch of the updated versions.

There is no information as to what processor the MacBook Pro will use. Meanwhile, Intel has launched its fifth generation 14nm Broadwell processor including Intel Core i5-5675C and Core i7-5775C.

As for the iMac, there is not much information, apart from the delayed shipping for the higher-end 27in iMac powered with a 3.4GHz processor and without Retina display.
